Swap was not easy at all, yes it is 6 speed & ill post more pics and videos as time progresses. As far as the transfer case it has been modified, so are the axles all around. Which was the first question raised if the XI can hold the power of the M3 & I'm proud to say that there were 3 BMW CERTIFIED master Tech's were working on my swap. If anyone wants further info on this swap contact impressive auto center and they will be more than happy to help you out if interested in this swap.
